How to treat bites from household fleas? - in detail
Flea bites appear as small, red papules, often clustered in groups of three. They itch intensely and may develop into raised welts or develop secondary infection if scratched.
Immediate care
- Wash the affected area with mild soap and lukewarm water to remove irritants.
- Pat dry; avoid rubbing, which can worsen inflammation.
- Apply a cold compress for 5–10 minutes to reduce swelling and numb itching.
Topical options
- Over‑the‑counter hydrocortisone 1 % cream reduces inflammation; limit use to 7 days.
- Calamine lotion or a 1 % menthol‑based gel provides soothing relief.
- Antihistamine creams (e.g., diphenhydramine) counteract histamine‑driven itching.
Systemic relief
- Oral antihistamines such as cetirizine 10 mg or diphenhydramine 25 mg every 6 hours alleviate pruritus.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200 mg) lessen pain and swelling.
When infection is suspected
- Look for pus, increasing redness, or fever.
- Seek medical evaluation; a physician may prescribe topical antibiotics (mupirocin) or oral antibiotics (dicloxacillin) if bacterial involvement is confirmed.
Prevention of recurrence
- Vacuum carpets, upholstery, and pet bedding daily; discard vacuum bags promptly.
- Wash pet bedding and blankets in hot water (≥ 60 °C).
- Treat pets with veterinarian‑recommended flea control products (topical spot‑on, oral chewables, or collars).
- Use insecticidal sprays or foggers approved for indoor use, following label instructions and ventilating the space afterward.
Special considerations
- Children, pregnant individuals, and immunocompromised patients should avoid potent topical steroids; consult a healthcare provider for alternative management.
- Individuals with known skin conditions (eczema, psoriasis) may experience exacerbated symptoms; monitor closely and adjust treatment accordingly.
If symptoms persist beyond 48 hours despite appropriate care, or if systemic reactions such as hives, difficulty breathing, or swelling of the face occur, obtain emergency medical attention immediately.
